Detects gamma rays in the range 20 mR/h to 120 mR/h and soft beta rays in the range 100 to 1800 units (points). This enables reliable monitoring of both common radiation types with a single module. Alarm function - Built in sound and light alarm to provide immediate notification when radiation levels exceed thresholds. Easy MCU and LCD integration - Output interface can be connected to a microcontroller and then displayed on an LCD for custom readouts and logging. broad tube compatibility - Supports most Geiger tubes such as M4011, STS-5, SBM20, J305, etc., and can operate with Geiger tubes in the 330–600 V voltage range. 2-3 practical use scenarios - Educational labs and student projects to visualize radiation detection and data display. - Field radiation surveys and safety checks in industrial or research environments. - DIY Geiger counter projects that require MCU integration and LCD readouts. Key benefits - Flexible detection of gamma and soft beta radiation with a wide tube voltage range. - Reliable alert system (sound and light) for quick awareness. - Easy data interfacing for custom displays and data logging. - Broad tube compatibility reduces the need for multiple modules.
